Rover V8 Conrod bearing scores

[cinquecento]

I'm keen on rebuilding my RV8 engine one day..so I bought a $50 wreck of an engine with unknown history to pull apart, measure and learn.

I pulled a conrod out and am a bit stuck on why the outside of the conrod bearing is more scored than the inner. The inner surface looks quite good but I don't quite get why the OD would be scored. It has tangs to stop it spinning yet there are visible scrapes along the outside of the bearing surface.

Any ideas why?

Thanks for helping Peter..here's a hopefully better quality image of the bearings

Can you actually feel scoring with your finger nail?

Hi Mike,

Yes..but very faintly.. I don't know the manufacture (no markings)...

Thanks everyone for your comments..
